TELEPHONE-TRANSMITTER HOOD.

SPECIFICATION forming part of Letters Patent No. 759,428, dated May 10, 1904.

Application filed October 29, 1901. Serial No- 80,398. (No model.)

To (LZZ whmn it may concern:

Be it known that I, ROBERT D. FANNON, a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Telephone-Transmitter Hoods, of which the following is a specification.

My invention is for use upon a desk-telephone transmitter, and is designed to produce an apparatus by the use of which a desk-telephone can be employed without anybody who may be in the vicinity at the time being able to hear the message transmitted.

To illustrate the embodiment of my invention, I annex hereto two sheets of drawings, in which the same reference characters are employed to designate identical parts in all the figures, of which Figure 1 is a perspective view of a desktelephone having my invention applied to the transmitter, but with it in its inoperative position. Fig. 2 is a rear elevation of the attachment; and Fig. 3 is a side elevation, in central section, with the wings as opened in full lines and as closed in dotted lines.

In carrying out my invention I employ a split clamping-ring a, which is adapted to be clamped upon the transmitter, preferably with a rubber band or ring 6 interposed. Secured upon this ring a is a casing 0, preferably made of light sheet metal and of the shape best shown in dotted lines, Fig. 3. The edges of the openings are covered with rubber d, and the opening is so shaped as to receive the mouth of the user. To accommodate the nose while completely inclosing the lips, a depression 6 is formed in the upper sides of the easing. The edges at f project forward to meet the cheeks and at the bottom at g to extend beneath the chin. The hood or casing c is so located and the aperture so shaped as to bring the lips to the proper distance from the mouthpiece h and to prevent the sound of the Voice escaping from the hood.

In carrying out my invention I split the hood into four wings 1', each of which is pivoted at is to the front edge of its ring (0. Staples Z are secured to the back of each wing near its pivot and a spring-ring m is passed through the staples and formed with the outwardlyturned ends a, so that by pulling the ends together the diameter of the ring m is increased, so that the wings can be folded together to form the hood ready for use. When there are no auditors or the message does not require privacy, the wings stand open in the position shown in Fig. 1. As the diameter of the ring must be increased to move the wings from either position to the other, its tension serves to hold the wings yieldingly in either position. I preferably also cover the meeting edges of the wings with rubber, as at 0.

By my invention it will be apparent that I have produced a simple contrivance by which the ordinary desk-telephone can be used when desired with substantially the same pivacy as if a booth were employed.

What I claim as new, and desire to secure by Letters Patent of the United States, is

1. Atelephone-transmitter hood consisting of the ring adapted to be secured to the transmitter-casing, with the wings secured thereto and adapted to be folded together to form a hood, and means for holding said wings yieldingly in either position, and means for simultaneously folding said wings together.

2. A telephone-transmitter hood consisting of the ring adapted to be secured to the transmitter-casing, with the wings pivoted thereto, and having the staples Z on the back thereof, and the spring-ring m passing through said staples for the purpose described.

3. A telephone-transmitter hood consisting of the ring adapted to be secured to the trans mitter-casing, with the wings secured thereto and adapted to be folded together to form a hood, and means for holding said wings in either position.

4:. A telephone-transmitter hood consisting of the ring adapted to be secured to the transmitter-casing, with the hinged sections carried by the ring and adapted to be folded together to provide a hood.

In testimony whereof I affix my signature in presence of two witnesses.

ROBERT D. FANNON.
